Looking for smart cover for Android?Now, you can use a normal cover with this app, the cover just becomes the smart cover. Just open/close the cover to turn screen on/off. Or you can just turn screen on/off just by touch the proximity sensor.

P.S.1. After running big app system may kill this app, you can use shortcut or notification to restart this app.2. When leaving app using back button not home, otherwise the setting page may show again when screen on. 3 If you want to uninstall this app MUST deactivate device admin first.4. I use force screen off after turning screen on without unlock, so even if you touch the screen, the screen also will turn off unless finishing unlock. Because Android 4.1.2 and 4.2 have wakelock bug. It doesn't auto turn screen off.

If you just want auto screen on, you can use my another app "Auto Screen On", it has g-sensor and proximity sensor to screen on, and has log function to watch how the app work. And it's free and no ads.

Some tablet may not have proximity sensor, please check it first. If the device doesn't have proximity sensor, it would show "the device doesn't have proximity sensor".Please don't give me one star just because your device doesn't have the proximity sensor.
